BPR1M492
BPR1M492 is a brain-penetrant μ-opioid receptor (MOR) agonist an in vitro EC50 of 0.93 nM in the cAMP inhibition assay and 0.004 nM in the FLIPR Ca2+ assay without a clear signaling bias between cAMP and β-arrestin-2 pathway. BPR1M492 is a cAMP-biased nociceptin-orphanin FQ opioid peptide agonist. BPR1M492 is a weak cAMP-biased δ/κ-opioid receptor agonist. BPR1M492 demonstrates potent in vivo antinociception and can be used for pain research.

BPR1M492 (compound 56) (336 s) activates MOR of CHO-K1 cells expressing human MOR and Gα15 (CHO-K1/hMOR/Gα15) with 91.7% maximum efficacy[1].
BPR1M492 fully agonizes MOR with an EC50 of 0.93 nM by the cAMP assay and NOP with an EC50 of 52.89 nM by the cAMP assay[1].
BPR1M492 weakly agonizes DOR with an EC50 of 730 nM by the cAMP assay and KOR with an EC50 of 2410 nM by the FLIPR Ca2+ assay[1].
BPR1M492 (CHO-K1 cell) effectively recruits β-arrestin-2 on MOR with an EC50 of 161 nM[1].
BPR1M492 (CHO-K1 cell) exhibits nearly no effect on β-arrestin-2 recruitment for NOP and KOR, and a partial effect for DOR with an EC50 of 2883 nM[1].
BPR1M492 fails to block the NMDAR ion channel at 3 μM and inhibits CYP1A, 2B6, 2C8, 2C9, and 3A with IC50s > 100 μM[1].
BPR1M492 inhibits CYP2C19 with an IC50 of 26 μM and 2D6 with an IC50 of 2.1 μM[1].
BPR1M492 inhibits hERG with an IC50 of 1.92 μM[1].

BPR1M492 (0.168 mg/kg; s.c.; 12 min) takes effect within approximately 5 minutes after subcutaneous (s.c.) administration in hMOR+ and mMOR-/- mice which indicates that BPR1M492 shows potential as an analgesic for postoperation[1].
BPR1M492 (0.054 mg/kg-0.162 mg/kg; s.c.; 30-120 min) produces potent antinociception and shows smaller reductions in oxygen saturation and respiratory rate in the incisional pain model in hMOR+ and mMOR-/- mice than TRV130 under the present dosing conditions[1].
BPR1M492 retains effective antinociception in the incisional pain model in hMOR+ and mMOR-/- mice and shows the clearest improvement in withdrawal-related behaviors in hMOR+ and mMOR-/- mice relative to TRV130[1].
